PATENT OFFICE 4 Claims.

This invention relates to barrel or basket making machines and more particularly to machines for stapling the hoops around the barrels after the staves have been arranged in barrel or basket form and temporarily secured in place.

In machines of the above mentioned type there is a tendency for the edge of the staves to buckle out of alinement under the impacts of the stapling devices. This causes an uneven surface around the center of the barrel and therefore an imperfect barrel. One of the objects of the present invention is to provide means for holding the staves in correct position during the stapling to prevent the slipping of the edge of one stave inward or outwardly relative to the adjacent stave.

A further object is to provide means which will hold the center of the barrel in a more nearly perfect circle, thereby resulting in barrels having better appearance and a more perfect and uniform shape.

Further objects and advantages will become apparent from the description which follows.

Referring to the drawing which is made a part hereof and on which similar reference characters indicate similar parts:

Figure l is a front elevation of a portion of a barrel stapling machine showing my device and Figure 2 is a section on line 22 of Figure 1.

In the drawing numeral it] indicates a portion of the frame of abarrel making machine having a shaft l l on which conventional anvils and other necessary mechanism, not shown, are mounted, and on which the barrel I2 is mounted. A shaft I3 supports blocks M which carry stapling devices l5, these stapling devices co-operating with anvils, not shown, on the shaft ll within the barrel. Positioned within the barrel is a pair of brackets 16. These brackets may be secured to the shaft H by a bolt ll. The brackets support a channel member 18, which may be secured thereon by bolts l9. Rollers 29 are rotatably supported in arcuate formation in the sides of the channel member and extend beyond the edges of the sides of the channel so as to engage the A channel member 21 having rollers 22 is mounted outside the barrel so that the barrel will be held between the inner and outer series of rollers. The channel member 2| is resiliently mounted in any suitable against external abutment flanges 29 of the 23 which is secured at its lower end to the channel member 2| and slidably carried by a block 24 mounted on the shaft It. To the upper end of the bar 23 is secured a cross bar 25. Brackets 26 may be rigidly secured to block l4. These brackets carry bolts. 21 which extend through holes in the ends of the bar 25. Compression springs 28 are confined between the heads of the bolts and the side of the bar 25 and tend to urge the rollers 22 against the staves of the barrel. The tension of the springs 28 is sufficient to hold the staves of the barrel in correct position. If desired the tension on the spring may be increased by turning down the nuts 29.

The series of rollers which are arranged in an arc corresponding to the arc of the barrel at thepoint where they engage the barrel, not only pre-, vent the edges of the staves from buckling in or out but also tend to form a more nearly round barrel at its center.

While the machine has been described as for use in barrel making it may obviously be used in basket making. The descriptive terms, therefore, are not to be regarded as in any way limiting the scope of the invention but rather for the purpose of clearness and conciseness.

It will be obvious to those skilled in the art, that various changes may be made in my device without departing from the spirit of the invention and therefore I do not limit myself to what is shown-in the drawing and described in the specification but only as indicated by the appended claims.

What I claim is:

1. In a barrel making machine, a support for a barrel, a plurality of rollers mounted on said support and adapted to engage'the interior of the barrel, a second support having stapling devices mounted thereon, a plurality of rollers resiliently mounted on said last named support and adapted to engage the exterior of the barrel in advance of, following and in axial alinement with said stapling devices and in opposition to the rollers on the interior of the barrel.

2. In a machine of the kind described, a support for a barrel, a support for stapling devices, stapling devices mounted thereon, an arcuate member having barrel engaging rollers mounted thereon at each side of the stapling devices, means for yieldingly supporting said arcuate member, and a bracket fixed within the barrel having rollers engageable with the interior of the barrel in opposition to the resilient exterior engaging means.

3. In a machine of the kind described, a support for a barrel, a support for stapling devices, stapling devices mounted thereon, an arcuate member having barrel engaging rollers mounted at each side of the stapling devices, the rollers being engageable with the barrel in advance of and following the point of engagement of the stapling devices with the barrel, means for yieldingly supporting the said arcuate member, a bracket fixed within the barrel, said bracket having rollers engaging the interior of the barrel in opposition to the exterior engaging means.

4. In a machine of the kind described, a support for a barrel, a support for stapling devices,

stapling devices mounted thereon, an arcuate member having barrel engaging rollers mounted thereon, means for yieldingly supporting said arcuate member, and means for supporting rollers within the barrel in engagement with the interior of the barrel in opposition to the rollers engaging the exterior of the barrel.
